MIDGET AUTOMATIC RECORD BRUSH.

Application filed March 19, 1923. Serial No. 626,192.

To all whom it may concern:

Be it known that I, CORY 0Z1 HUNTING- TON, a citizen of the UnitedStates, residing at Galvin, in the county of Lewis, State of Washington,have invented a new and useful Brush for Use on Phonograph Records,Designated and Named by Me as the Midget Automatic Record Brush, ofwhich the following is a specification.

This invention has to do with improvements in brush attachments orrecord cleaners designed to cooperate with the reproducer of phonographsor similar machines.

The object of my invention is to provide a simple yet effective device,made of comparatively thin metal, which is adapted to slip over thesound box of a phonograph in such position as to dispose its brushmember in advance of the needle, and including a shank portionconstructed and arranged to cooperate with the stylus when in position,by means of which relative displacement of the attachment, once it hasbeen mounted in operative position, is prevented. Other objects andadvantages of the invention will be hereinafter set forth and the novelfeatures thereof defined by the appended claims.

In the drawing:

Figure 1 is a side elevation of a sound box showing my invention inposition thereupon Figure 2 is a fragmentary sectional view taken uponthe line 11-11 of Figure 1;

Figure 8 is a perspective View of my attachment alone;

Figure 4 is a detail fragmentary view of the end of the shank portionshowing the application of a detachable brush member;

Figure 5 is a top plan view of the portion shown in Figure 4; and

Figure 6 is a plan view of the blank or base plate upon which the brushused in the detachable form is mounted.

Referring to the drawing and specifically describing the invention, itwill be observed that the holder is composed of a relatively narrowstrip of thin metal the upper portion 2 of which is curved to conform tothe periphery of the sound box which is embraced thereby when theattachment is placed in position. Diametrically opposite grippingflanges or fingers 3 arranged at spaced points engage the sides orlateral faces of the sound box so as to hold the attachment firmly inposition thereupon with the lower or shank portion of the attachmentextending downwardly inrear of the needle andthen forwardly to a pointwhich will dispose the brush member 1 attached to the end of the shankin advance of the needle. The shank portion is provided with an aperture4 through which the needle of the sound box is inserted in position andobviously the cooperation of the shank portion with the needle in thismanner tends to hold the attachment in position against relativedisplacement and maintains the brush member in proper relation to theneedle so as to insure its operation over the path which is followed bythe needle. The brush member 1 may be of felt or other similar materialand in the operation of the device there is just sufiicient tension inthe use of the spring metal to insure a pressure upon the record whichwill clean the grooves effectively so that the sound reproduced by theneedle will be most clearly reproduced, the pressure being insufficient,however, to cause any retardation or drag upon the movement of therecord in operation.

In Figures L to 6 T have illustrated a modified form in which the brush5 includes a base plate of rectangular form having bendable tabs 6 whichare bent over the headed extremity of the shank portion of theattachment as clearly shown in the said figures. This will enable at anytime the replacement of the brush without removal of the attachment orwithout renewal of the complete attachment and it is therefore ofdecided advantage to make. the brush member detachable as in this form.

Having thus described my invention, what I claim as new is:

1. A cleaner attachment for reproducing machines comprising a bodyportion having means adapted to engage the sound box of a reproducingmachine and a shank portion with which the needle of the sound box isadapted to cooperate at an intermediate point, said shank portionextending in advance of the needle, and a brush member mounted on theend of the shank portion.

2. A cleaner attachment for reproducing machines comprising a bodyportion having gripping means to engage the sound box of a reproducingmachine and a shank portion provided with an opening through which theneedle of the sound box is adapted to extend, and a brush member mountedupon the end of the shank portion.

3. A record cleaner attachment for reproducing machines comprising astrip of relatively thin material adapted to embrace the periphery ofthe sound box of a' reproducing machine having laterally projectinggripping fingers to engage said box and a downwardly extending shankportion engaging the end of the needle arm and extending to a point inadvance of the needle,

and a brush carried by the end of said shank portion, said shank portionhaving an opening through which the needle is free to extend.

In testimony that I claim the foregoing as my own, I have hereuntoaflixed my signature in the presence of two Witnesses.
